Categories of restraints. Three general categories of restraints existâphysical restraint, chemical restraint, and seclusion. Physical restraint. Physical restraint, the most frequently used type, is a specific. intervention or device that prevents the patient from moving freely or restricts normal access to the patientâs own body.

Type 4: Self-Ligating Braces. Similar to traditional metal and ceramic braces, self-ligating braces make use of the bracket and wire system. This may be the type of braces that most orthodontist use today, but many still use a more traditional system. This type of braces uses brackets with clips or doors that hold on to the wire, instead of the rubber band tie system. These braces are supposed to hold on to less food and be less painful than other types of braces, and they are also supposed to reduce the number of trips to the orthodontist the patient has to make.
